Application filed January 6, 1925. Serial No. 747. l

This invention relates to washing machines.

An object of this invention is to provide a washing machine in which a ,drum adapted to hold thev clothes is rotatably mounted 1n a tank partiallyl filled with waterand constructed in suc a manner that rotation of theY drum will cause a circulation of water to lpass in and out of the clothes and drum.

` nother object of theinvention is to provide an' electric switch controlling a vmotor in connection with an operating mechanism adapted to stop the drum of the washing.

machine in a positionthat the door carried by the drum may be opened.

A further object is to provlde a washing machine having a rotatable drum construct- Y ed in such a manner that the clothes theret in will be turned overateach revolution of the drum.

These objects are attained by the disclosure herein set forth by the following description of the accompanying drawings, the novel features of the invention beingpointed out in the appended claims.

Referring to the drawings:

VFi 2 is a longitudinal section taken on the line 2-2--of Fig. 1; v

Fig. 3 is a transverse section taken on the line 3-3 of. Fig. 2;

Fig. 4 is a fragmentary section taken on' the line 4--4 of Fig. 2;-

Fig. 5 is an enlarged fragmentary front elevation showing an electric switch an'd opening mechanism?" Fig. 6 is a horizontal section taken on line 6-6 of Fig. 5;

Fig. 7 is a view analogous to Figure 6;

Fig. 8 is a vertical section taken on line 8-8 of Fig. 5; and

Fig. 9-is a section Fig. 5. f

Referring to the' accompanying drawlngs wherein similar reference characters designate similar parts throughout, 10 designates a base upon which is mounted a frame designated at 11 consisting -of end plates 12 and 13 and side plates 14 and 15. The frame supports a tank, generally designated at 16. The tank has a curved bottom 17, vertical side walls 18 and 19 terminating in flanges taken on line 99 of 20 and 2 1, .a front wall 22, and a rear wall 23 having` flanges 24 and 25 respectively.

A bearing 26 is secured to. the front wall 22 and has a bore 27, 'a counter bore28, an externally threaded portion 29 and a gland 30adapted to compress packing 31 in the counter bore 28. A bearing 32 is secured to the rear wall 23 and has an opening 33 between arms 34. A drum 35 is axially mounted in the tank 16. The drum consistsof flat end plates 36 and 37, semi-circular eccentric side walls 38 and 39 joined at their extremities by perforated offset plates 40 and 41. The side wall 38 has an opening 42 closed by a door 43 having a suitable latch 44 and a hinge 45. The side walls 38 and 39 and the door 43 have a series of longitudinal inwardl projecting Arilii'es 46 having apertures 47 therein. The oii'set plate 41 projects inwardly and forms a baiie 48. A spider frame 49 is secured to the front wall 36 and has a central hub 50, in which is formed a square opening 51 having tapered sides 52. A spider' frame 53 is secured to the rear wall 37 and has a hub 54 in which is secured a spindle 55.' The. spindle 55 rests in the bearing 32, and the opening 51 in the hub 50 engages a square shank 56 having tapered faces 57 formed integral on a shaft 58 mounted in a bearing 26. v A leaf spring 59 is secured to the bearing 32 and engages the spindle in order to hold the hub 50 and the shank 56 tightly engaged. A beveled gear 60 is secured tothe shaft 50and meshes with a gear 61 secured toy a shaft 62 carrying a worm wheel 63 meshing with a worm 64 secured to a horizontal shaft 65 connected to a shaft 66 of a.' motor 67 by a coupling 68.

The gears and 61 are enclosed in a gear PATENT OFFICE.

case 69 fastened to upright angle irons 70' between horizontal angle irons 71 secured to the front plate 22. A second worm wheel 72 meshes with the worm 64 and is secured to a vertical shaft 73 which may -be used for operating a wringer (not shown). The

form depending bearings 78 and 79 adapted f to receive the ends of the shafts 62 and 73,

-surrounds the shaft 73, and a cover 84 is fastened to the gear case 69, thereby enclosing all the transmision.

A removable cover 86 rests on the flanges 20, 21, 24 and 25 of the tank'16. The bottom 17 of the tank 16 is provided with a longitudinal channel 87 in registration with anaperture 88 in the front plate 22. Water in the tank maybe drained by opening a valve 89 secured to the front plate 22.V A. switch, generallydesignated at 90, for controlling an electric circuit through the motor 67 is constructed as follows:

A box 91 formed of fiber, or other insulating material, is secured to the front plate 22 in which is pivotallymounted a bar 92 of conductive material adapted to engage a contact 93; A circuit being closed when the bar 92 engages the contact 93 through insulated conductors 94 and 95 leading to the motor 67 and a suitable .source of electric energy.

A handle 96 formed of insulating material, is secured to the bar 92, and a removable cover 97 is` fastened to the switch box by screws 98. A

Itis desirable that the drum 35 be stopped with the door 43 in a position that it may be opened as shown in Fig. 3, and is\accom plished by a switch operating mechanism generally designated at 99 constructed as follows:

One end of a shaft 100 is mounted in a bearing 101 secured to the front face of the gear case 69 and the other end extends through a bushing 102 in the wall of th gear case.

The shaft carries a fixed crank`104 and a vrocker arm 105 slidable on a square portion` `106. A shift lever 107 'having bifurcat'ed ends 108 engaging the rocker arm, is pivot'- ally mounted on a pin 109 carried by brackets 110 secured to the top of the gear case. An expansion coil spring 111 surrounds thev shaft and is' interposed between the crank 104 and rocker arm 105. L l.

A tappet 1 12 is secured to the inner face of the bevel gear 60 an'd a link 113 is pivotally connected -to the crank and handle 96 of the bar 92.

registration with thetappet 112.

When it is desired to stop the machine the shift lever is pulled forward and temporarily held in the position shown in.. dotted lines in Fig. 8, the movement of which will i Lsseaa brin the rocker arm into the path traversed by lt e tappet. (See Fig. 7). As the drum rotates the tappet Will engage and lift the rocker arm, thereby rocking the shaft and crank, which in turn will open the switch by means of the link, as shown in Figure 1, thus break the circuit to the motor. The drum will stop rotating shortly after the circuit to the rrotor is out olf, and will stop in a position that the door ma be o ened as the door and tappet are in Xed re ative positions.

When it is desired to use the washing machine the cover 86 is removed and the door 43 opened. Water is poured into the drum 80 through the opening 42 and will seek a level in the tank through the apertures 47, the clothes to be washed are placed in the drum and the door 43 is closed and latched. When the washing machine is in operation the S5 drum rotates in the direction of the arrow A. (See Fig. 3). As the drum rotates the clothes therein will be raised in the water due to the action ofthe eccentric side walls and turned over by the riiile. The water in the drum will seek a level thereby circulating in and out of the clothes.

From' the construction it will be seen that. the washing machine is comparatively simple in construction and is very effective in performing its intended functions, as there is a continual circulation of water through the clothes, the rotation of the drum causing a pumping action through` the apertures therein.'y 1 J It is to be noted that in the operation of my washing machine gas it rotates in the direction of lthe arrow Aas shown in Fig. 3, when the perforated offset plates 40 and 41 pass through .the water the water is injected 165 with considerable force. through the apertures and also as the apertures 47 in the corrugations forming the riflles .are on the apex of these corrugatlons the Water will be prof jected radially inwardly from said apertures. At the same time the clothes are givenI a rolling and turning movement by the rililes and the projecting ba-le 48 tends to lift the clothes above "the level of the water inthe washingmachine and drop the clothes to ,the 115 lowest side of the rotating drum. Therefore the clothes are not merely subjected to a turning action in the water but' are also subjected to jets of waterimpinginggon the clothes as above mentioned It will be understood that various changes inthe detail of construction m ay be made without departing from the spirit or scope of the inventlon as defined by .the appended claims. l 1
